what's the purpose of injecting a dependency

Question

In AngularJS, what's the purpose of injecting a dependency as an array element and as an argument?

For example:

.controller('foobar', ['$scope','$mdDialog', function ($scope, $mdDialog) {}

But

.controller('foobar', function ($scope){}

is also valid?

See [AngularJS Developer Guide - Dependency Annotation](https://docs.angularjs.org/guide/di#dependency-annotation). — georgeawg, Jul 03 '17 at 15:29

When you minify, the argument names will change and Angular won't be able to resolve them; hence, the array form tells Angular which ones to inject.
